Bubble nebula - Nov2022

The Bubble nebula (NGC 7635) and an open cluster M52 in the constellation Cassiopeia. They appear next to each other but the nebula is ~11000 LY away while M52 is closer at a distance of only ~5000 LY. The bubble is about 10 LY across and is formed because of the intense radiation from the star inside it pushing the interstellar gas and dust.
